As you successfully complete the intricate gestures and tongue-tying syllables of this spell, you conjure a featureless black sphere of nothingness. Matter that touches the sphere disappears, causing a slight breeze to form that blows endlessly in the direction of the all-consuming blackness.

You create a terrible sphere that destroys anything it touches. The sphere flies up to 30 feet per round. The sphere stops moving when it enters a space containing a creature, automatically striking it. You must actively direct it to a new target as a move action.

When struck by the sphere, a subject takes 2d6 points of damage per caster level (maximum 40d6). Any creature reduced to 0 or fewer hit points by this spell is disintegrated, leaving behind only a trace of fine dust (though its equipment is unaffected). When used against an object, the sphere disintegrates as much as one 10-foot cube of nonliving matter. A creature or object that makes a successful Fortitude save is partially affected, taking only 5d6 points of damage. If this damage reduces the creature or object to 0 or fewer hit points, it is disintegrated.

The effects of the sphere count as a disintegrate spell for the purpose of destroying a wall of force or any other spell or effect specifically affected by disintegrate. If the sphere moves beyond the spell's range, it winks out.

Material Component: A pinch of dust from a disintegrated creature.
